RFR: JDK-8072754: Getting read of unnecessary sun.misc.Version in the test

[Alexander Kulyakhtin]

Hi,

Could you, please, review a small fix below.

bug: https://bugs.openjdk.java.net/browse/JDK-8072754
webrev: http://cr.openjdk.java.net/~eistepan/~akulyakhtin/8072754/webrev.00/

The tests uses sun.misc.Version to check if the JVM version is greater than a certain version.
For the JDK 9 the condition is always true and the usage of sun.misc.Version thus can be eliminated.

Best regards,
Alex
